To all whom it may concern:

Be it known that I, OHA LEs A. Hominuno, a citizen of the United States,residing at Devine, in the county of Medina-and State of Texas, haveinventeda new and useful Retaining-Ring, of which the following is aspecification.

By way of explanation it may be stated that automobile operatorsordinarily have at their command, one or more tire casings which are notuse. These casings may be new or they may be casings which, hav ing beenused to a considerable extent and being more or less unfit for usealone, stlil are strong enough to be used as a protection for anothercasing.

In view of the foregoing, this invention aims to provide means whereby atire casing,

either new or used, may be assembled withanother tire casing, preferablybut not nee cssarily of identical form, to serve as a protectioh for thelast named casing.

WVith the above and other objects in view which will appear thedescription proneeds, the invention resides in. the eombination andarrangement of parts and in the details of construction hereinafterdescribed and claiiml it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made Within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawingsz Figure 1 shows in transverse sectionyadevice constructed in accordance with the .present invention, and of theform delineated in Fig. 2;

Fig. .2 is a fragmental side elevation showing a portion of thestructuredepicted in a Fig. 3 is a. fragmental elevation showing amodified form of the invention.

In the accon'ipanyi11g drawings,' the" numeral 1 indicates a rimprovided with flanges 2. At 3 there is shown a main tire casing havingbeads 5 intcrengaged with the flanges Disposed within the maincasin'gfiis an inner tube 4. The foregoing details are common. and no novelty isclaimed for them, sa ing in so far as they may enter into combinationwith the other elements to be described hereinafter.

Surrounding the main casing 3 is an outer auxiliary casing 6, which,ordinarily is constructed exactly like the main casing 3, although asimilarity between the two caslngsis not insisted upon. The auxiliarycasing 6 is provided'with beads 7.

The invention comprises a pair of side rings 8 including clcnchenflanges5) rcceiw ing the beads 7 of the auxiliary casing (i. The rings 8tproject inwardly beyond the nner edges 0 the heads 7 and rest on theflanges 2 of the main rim 1.

The inner edges of the flanges 9 are concaved slightly as sho'wn at 18and coii 'ierate with the flanges 2 to prevent the side rings 8 frommoving outwardly, the flanges 9 being rounded as shown at 15), tocoiiperate with the main casing The rings 8 are supplied at their endswith integral lugs 10 connected by a bolt 11 and a nut 12, or in anyother suitable manner. a As shown in Fig. 3 of the drawings, the

rings carry plates 14 held ,to the ends of the rings ,by securingelements 15. The plates 14" carry lugs 16 having the same functions asthe. lugslO, the lugs 16 being connected by a bolt 11 and a nut .12, orin any other suitable manner as hereinbefore described.

From the foregoing, it ,will be observed that this invention provides anovel means whereby one casing may be assembled with another, as aprotection therefor.

Having thus described the invention, What is claimed isz- In a device ofthe class described, a rim including flanges; a main casing having edgescoactlng directly with the flanges; an

auxiliary casing disposed outside of the main casing and provided withclenc'her beads; and rings having cleucher flanges receiving the beadsof the auxiliary casing, the rings resting on the outer cdges oftheflanges of the main rim and terminating atsaidouter edges. thereby topermit the edges of the main casing to court directly with the flangesof the main rim.

In testimony that I claim the foregoing as my own, I have hereto affixedmy sigmv hire in the presence of two witnesses.
